As the rollers 9, l rotate the material is forced through the nozzlesthe rate of flow being proportionate tov the speed of said' rollers. Itmay be found that under some circumstances the rate of discharge is toorapid and in order that this difficulty may.

20...some circunistancesit inay be 'feund suf- 'ficient tofrernploy:only one such roller.`

In order that the material within the' hopper may be retained at thedesired'cfonsisteney the hopper lis provided with a jacket throughwhich' hot water is caused to circulate by means of a pump 16 mountedupon the pedestal l, the pedestal containing a, heaterl heated by s't'eam supplied threugh the pipe 18 and controlled by the coek .19.2`Oindicates the return pipe. IThe hot water is'I supplied tothe jacket15 thifougii ne sentie pipe 21.

Sec r d o the spin lle of the roller as shown in 4, is ashaftj23. A 23Aaindicates ,a 'clutch whereby the shaft 23 may be clutched to a shaft2'2,said clutch being operated by-a rod 23b previded with a handle 23C, Fig.ll, whereby not only may clutch 23? be operated but the hopper may beswung by thesaine .hand horizontally in all directions.

The rod 23B at its inner endA is provided with a cam surface engaging asimilar surface upon a pin or stud carrying a fork 23d which straddles abobbin 23, `Fig. 4. .A spring opposes themovement of the bobbin in onedirection. By turning the rod 23b in one direction the engaging camsurfaces act to move the fork and the pump is declutched.

Rotary movement of the rod in the other direction willpermit the springto clutch the pump to the spindle of pinion 2 4.

The shaft 22 carries a bevel wheel 24 in gear with a second bevel wheel25 having` a shaft 25a secured ina sleeve 26 having at its upper end abore of square cross-sectional outline and with whichengages asquareeigtension 2.7 uponthe end of verticallydisposed shaft 28, thearrangement being such as to VApermjt of universal. 'njfovement o f thehop,per without jamming the end of the sharm. i

The u" per Vend of the shaft 28 vprvitled with -eiktensibn y2,9 similarte 4that l L29-Y @haar a rag. Arsengagag the sleeve 29a is a short shaft30 provided with a bevel wheel 31 engaging a second wheel 32 freelymounted upon the aforesaid rod or bar 3'. Preferably the sleeve 292l isof sufficient length to, permit the shaft 28 to be lifted a suflicientdistance to clear the sleeve 26 when the shaft 2'8 may be removed.

Also freely mounted upon the rod 3 is a worm wheel 33', Figs. 1 and 6,said worm wheel being driven through gearing to be presently more fullydescribed.

Provision 1 is made whereby the bevel wheel 32` is -f rictionagllydriven by the worm wheel 33, thev friction contact between the partsbeing adjusted by means ofthe leverf` 34 pivotally mounted at 351an"dwhich lever at one en'd engages' a b'obbin 36 between which and theinner face of worm wheel 33 is inserted a helical spring 37, ay ball orlike bearing 38 being inserted between the end of the springand the faceof the said worm wheel33. 39 indicates a screw having a milled head andsupported by a projection- 4O1upon a bracket 41 carrying the' sleeve29a. The screw 39 engages the free endr of! the lever 34,: said screwserving to' regulate the compression of springw37 and consequently theextent of the frictional contact between worin wheel 33'` and theV bevelwheel 32. By Vthis means it is possible to so arrange' the frictionbetween the parts, that should the material in the hopper solidify orotherwise attain such a degree of visc'sity as would otherwise cause theprojections of rollers 9, 1 0 to become damaged the parts will slip andpermit the rollers to remain' stationary. Preferably a casing isprovided for the adjusting screw 39 whereby samemay be protected fromoperation by persons other than those competent to effect the desiredadjustments.

Tlieinotion for the variousparts is secured by means of'variablespeedgear coinprising a shaft 42 mounted on a swing bracket 43, said shaftbeing provided with fast vand-loose pulleys 44, 45, The bracket 43 ispivotally mounted upon the arin 46 forming part of a plate 47 mountedupon the upper end of the part 2 of the pedestal l. vThe plate 4'?carries brackets 48 in which is mounted a shaft 49 and mounted upon thesha-ft just referred to and shaft 42 are opp'ositely coned .pulleys 50,5l around which passes a belt r52 shown. in Fig. The belt is adjustablelengthwise of the pulleys 50, 5l by the forl 53 carried by the screw 54operable by the hand wheel 55.

In order that the belt 52 may be tensined, when so desired, a swivel nut56 is provided upon an extension 57 ef the swing bracket 4.3, a aree 5spagina mais. and autres' 21,.:w0rm. 60a .engaging per end with a disc 67slotted to receive a head 67a upon a stud 68 upon which is pivotallymounted an arm 69 pivotally connectedy to the hopper. The arm 69 isslotted to permit the passage of the stud 68, said stud movinglongitudinally of said arm during the rota,- tion of the disc 67. 70indicates a pinion upon the spindle of disc 67 engaging a pinion 68 upona second disc 7l such Yas that 67 just before `referred to and to whichdisc there is secured a stud 7 2 engagingY the outer end of the armv 69.By this means an eccentric motion is imparted to the hopper in order toproduce decorative patterns upon the goods. n n

The parts may, however, be readily disconnected to enable the hopper tobe moved by hand by removing the studs 68 and 72 to free arm 69 whichmay then be disconnected from the hopper.

73 indicates apulley secured to the spindle carrying pulley 63 andbyvwhich pulley motion is transmitted through belt 73 to a pulley 7 4:upon the pump 16.

75 indicates a brake whereby the speed of the shaft carrying pulleys 63and 73 mayv be controlled by hand from the table carrying the goods, forWhich purpose a chain or other flexible body 76 is provided led around aguide pulley 77 to the desired point.
